IMPRovEMl-:N'r IN LAMPS.

Specification forming part of Letters Patent No. '71.354, dated November 26, 1867i.

To whom it may concern.-

Be it known that I, HENRY YOUNG, of YCinl `cinnati, Hamilton county, Ohio, have invented a new and useful Lamp-Burner5 and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

The object of this invention is to provide a lamp-burner which shall more fully come up to `the requirements of a smoke-consumer without4 a chimney than has been heretofore known.

` In theaecompanying drawings, Figure 1 is a vertical section of a burner embodying my invention inthe line x x, Fig. 2. Fig. 2 lis a perspective view of my burner, showing the same in position for lighting. Fig. 3 is a vertical section in the line y y.

A is the usual screw-threaded part, for the afxing of the burner to the body of the lamp, surmounted by a perforated flange, Bhaving an upturned rim, b. Within this rimis a glass pipe, C, connecting the fiange B to the plate Upon this frame is erected an upwardlyconverging` iiattened airdnct, El Pivoted to the frame D, at f, is a similar duct, F, which, when the lampis burning, occupies a similar position to the duct E,

Thev lduct F has a handle, f', to revolve the said but on the opposite side of the flame.

duct F away from the lamp-wick, to admit of lighting. The said handle is composedof wood, or some other slow conductor of heat,

`to avoid burning the fingers.

`Passing through the flange or plate B and part A is a usual wick-receiver, G, having a customary device, H, for raising the wick.` y This receiver rises to within about one-eighth of an inch of the level of the lower ends of 1 ducts nana F.

Upon the plate D, between the ends of ducts Eand F, are wings I, serving to nearly close y the apertures between them for about one-half i. `of their height. The wings are curved out- The wings also limit the `supply. of air from outside the burner to the` lower `part of the dame. p y

The handle `f is connected tothe duct F by means of a dat horizontal projection, K, from the said duet.

friction, retains the dn'ct in place.`

When it is desired to lightthe lamp ,the 1 duct F is placed as seen in Fig. `3; `and when 1 the wickis first kindled the said ductis adjusted f `to near proximity to E, `but not `quite to its 1 i usual position `when the lamp is burning. j This` adjustment allowsof` the ducts attaininga working heat., and the iiameto be kindled l above the saidv ducts, and insures a clear combustion and one free from smoke.1 The wick having become fully kindledand the ducts sufciently heated, theduct Fis advanced or i i ,closedup to its working` position. i

When used as a night-lamp the flame` may, p. be confined below the plate1D,11and. the light-` allowed to shine only through the glass tube G.

`I do not `confine myself to glassin the construction of connection `G5 but any `material might be used in its place answering the saine purpose as a slow conductor of heat.

I claim herein as new and of my` invention-.p i 1. The provision in a lamp-burner of an air.-` duct, F, so arranged as toadmit a movement` to or from the wick, substantially as stated.`

2. rIhe arrangement of the air-`ducts or tubes E F and wings I l, all constructed andsapi plied in the manner described, and for the pur.-`

pose set forth.

In testimony of whiehinvention Ihereunto i Set my hand.

The said connection, when the a duct F is brought in near proximity to the y. duct E, passes beneath a catch, J, which, by y
